MACHINE FOR WEAVING COILED-WIRE FABRIC.

SPECIFICATION foi-#ming part of Letters Patent No. 480,007, dated August 2, 1892.

Application tiled August 29, 1891. Serial No. 404.084. (No model.)

To a/ ZZ whom t may concern:

Be it known that we, ORLANDO P. BRIGGS and FRED L. BRYANT, citizens of the United States, residing at Chicago, in the county of Cook and State of Illinois,haveinventedacertain new and useful Improvement in Machines for IVeaving Coiled-Wire Fabric for Bed-Bottoms; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings,and to letters ot' reference marked thereon, which form a part of this specification.

Our improvement consists in certain additions to and improvements of the machine described in Letters Patent of the United States No. 348,150, granted to Orlando P. Briggs One ot' theadditions made to the machine described in said patent is automatic mechanism for periodically arresting the action of the fabric-shifting mechanism to allow the insertion of several coils into one coil-space to form in the fabric what is termed a cord Another addition to the Briggs machine is cutting mechanism at themiddle of the machine for automatically transversely dividing the fabric which has been woven of a length equal to the length of two fabrics to the end that a double-length fabric need not be cut by hand or on a separate machine after being removed from the coiling-machine. An-

@n other addition to the Briggs machine consists in certain grasping and releasing mechanism for holding the last-finished or marginal coil of the fabric whilea new coil is being formed and made to intertwine with the last-finished coil. In the machine illustrated in said Briggs" patent the last-finished coil hangs by gravity from the preceding coils and rests against a vertical wall and at a suitable distance above a table to allow the new coil to run forward upon said table and intertwne at each turn with thelast-linished coil. This is an operative construction; but our apparatus for engaging and determining the position of the last-finished coil operates with greater precision, and therefore adapts the machine to be operated at a somewhat higher rate of speed. Amongl the features of variation may be mentioned the form of mechanism used for shifting the fabric longitudinally toward and from the coiler, and the specific construction of the knife-operating mechanism forcuttingthecoilattheend of the machine adjacent the coiler and the mechanism for intermittently operating the fabricdrawing mechanism.

In the accompanying drawings, Figure 1is a front elevation of a machine embodying our' improvement, the coiler being in part omitted. Fig. 2 is a plan of the same machine. Fig. 3 is an elevation of the end of the machine opposite the coiler or left end of the machine as viewed in Fig. l.

Fig. 13 is a detail transverse section showing the margin of the fabric and the means for engaging and supporting the same in proper relation to the course of the coil being projected from the coiler. Fig. 14 is a similar view showing the last instead of the next to the last coil engaged by the reciprocating pins. Fig. 15 is a larger front elevation of the head of the machine, showing the coiler complete. Fig. 16 is a plan of the portion of the machine shown in Fig. let. Fig. 17 is a detail section of the wire-forcing rolls.

In said drawings,A is a frame upon which the operative parts ot the machine are supported. Said frame is twice as long as the length of an ordinary woven-wire fabric plus the space required for the coiler and gearing. It the machine be made for coiling the length of only one fabric, this frame may obviously be correspondingly shorter.

A is a horizontal carriage supported by wheels A2, arranged at each corner of said Fig. 5 is a section in line ot b of Fig.

IOD

frame and resting in ways A3, fixed upon the frame A parallel to the length of said frame. The same result may be obtained by applyinf)r the wheels A2 to the frame A and the ways A to the carriage A. The object of said wheels and ways is to provide a limited longitudinal reciprocation of the carriage A', as and for the purposes hereinafter set forth.

B is a band-wheel mounted loosely upon a driving-shaft B, which shaft is supported in bearings B2, suitably located upon one end of the frame A.

B3 is a bevel-gear loosely surrounding the shaft B and secured to the wheel B, and Bt1 is a bevel-gear meshing into the bevel-gear B3 and surrounding and keyed to the worin-shaft B5,Which worin-shaft engages the worm gearwheel B6 and imparts rotation to the latter. The worm-gear B surrounds and is keyed to a horizontal shaft B7, and upon said shaft B7, at one side of the worm gear-wheel B and keyed to said shaft, is a spur-gear BS, ineshing into a small spur-gear B2, mounted upon and keyed to the horizontal shaft B10. Surrounding the shaft B10 is a cam-wheel B11, provided with two cam-faces Z911.

B12 is a clutch-lever pivoted between its ends, as at 1112, and having its upper end in engagement with a clutch B13, which is keyed to the shaft B and adapted to engage the band-wheel B, so that motion may be transmitted from said band-wheel to said shaft B. The relation of said band-wheel, clutch-lever B12, and cam-wheel B11 is such as that when the clutch B13 is thrown into engagement with the band-wheel B the lower end of the arm B12 will be in the path of the cam-faces Z911 and ready to be moved by the latter when they pass said end. Said end may be provided with an anti-friction roller Z113, placed in such position as to make contact with the cam-faces 511. The said clutch is held normally in engagement with said band-wh eel by an expanding coiled spring B14.

From the foregoing it will be seen that if the band-wheel B is rotated continuously the gears B3 B4, wornrshaft B5, worm-gear B15, shaft B1, spur-gears B8 and B", shaft B10, and cani-wheel B11 will be operated continuously, while the clutch-lever B12, clutch B13, and shaft B will be operated intermittently, and that the interval during which the shaft B rotates will hold the same ratio to the interval during which it does not rotate as the ratio of the spaces between the cani-faces Z211 holds to the length of said faces. For example, if the length of each camface is only oneteuth of the space between the two camfaces the interval during which the shaft B does not rotate will be only one-tenth as long as the period during which it does rotate. The object in providing these continuous and intermittent movements is to afford means for periodically arresting the action of the coiler and at the same time providing conti nuously-moving parts, which may be treated as a source of movement for other portions of the machine, which are to operate during the suspension of the operation of the ceiling mechanism.

C is the coiler. As any suitable form of coiler may be used in connection with the other parts of the machine, and as the particular coiler illustrated in this specification is not our invention jointly, but contains improvements which are the invention of 'Fred L. Bryant, one of the parties hereto, it is deemed su fficient to herein describe said coiler only as to its general features. From the base C rise four bearing-posts C2, each of which has extending from its upper end downward through its middle a space in which are the bearing-blocks C3. Said bearing-blocks C3 form bearings for the horizontal parallel shafts C1 and (J5, C4 designating the lower of said shafts and C5 the upper of said shafts. Said shafts are geared to each other by spurgears C11 and C1, applied, respectively, to the shafts C4 and C5.

C8 is a spur-gear located upon the shaft t)4 and meshing into the other spn r-gear C2, suitably supported between the shafts C4 and C5, and in turn meshing into a spur-gear B15, mounted upon the shaft B. Upon the middle of the shafts C1 and C5 are located wireforcing rolls c1 and c5, respectively, which rolls bear upon each other and are turned when said shafts are rotated. The two middle posts C2 terminate above in arches C10, and a vertical screw C11 extends downward through each such arch and bears upon an expanding spring C12, which spring in turn bears upon the bearing-block C3, located in the adjacent bearin g-post C2. The lower bearing-blocks C3 have fixed positions in the lower portions of the channels or vertical spaces in the posts C2, so that the positions of the spurgears C1 and the wire-forcing roll are unyielding. Driving the screw C11 downward will cause the spring C12 to press the adj acent upper bearing-block C3 downward upon the shaft extending through Vsaid bearing-block, and said shaft will be pressed down so that the upper wire-forcing roll and the spur-geaps upon said shafts will be forced together.

C13 is a guide for leading the wires f to the wire-forcing rolls, and C11 is a guide to lead the wire from the forcing-rolls to the coilforming spindle C15. Said coil-forming spindle has around it a spiral passage andashell C16. The wire is forced through said spiral passage between said spindle and said shell and is thereby transformed into a coil, which passes off over the end of the spindle C15 into the channel D, to be hereinafter described.

D is a channel formed in the upper portion and lengthwise of the carriage Ain line with the spindle C3, so as to receive the coil projected from the coiler C, and at the side of said channel is a wall l to aid in retaining said coil.

D is a roller mounted upon and extending IOO IIO

IZO

lengthwise of the frame A at the rear of the channel D and arranged to be rotated, as will be hereinafter described.

D2 is a roller located above and parallel to the roller D and having its journals resting loosely in vertical guideways D2, so that it will rest by gravity upon the roller D or upon the woven-wire fabric E when the latter lies between said rollers. The roller D is rotated in the direction indicated by the arrow, and, together with the roller D2, serves to draw the coiled fabric away fromv the line in which the coils are formed. A non-rotary bar or plate maybe substituted for the roller D2, as is described in said Briggs patent. The surface of the roller D may also be provided with pins d for positively engaging the fabric.

The shaft B10, which has already been described as rotating continuously, has surrounding it loosely the spur-gear B14, and adjacent to said spur e gear a clutch B15 surrounds said shaft and is adapted to engage with said spur-gear and cause the latter to receive rotation from said shaft. Beneath, parallel to, and extending along the entire length of the carriage A is a shaft E, which receives motion from the spur-gearB14 through the spurgear E', with which it meshes and which surrounds and is keyed to the shaft E. The clutch B15 is normally in engagement with the spur-gear B11, so that the shaft E is normallyin rotation and ceases to rotate only when said clutch is disengaged from the spurgear B11. A clutch-lever B10 engages said clutch B15 and is pivoted between its ends at 510, and a contracting coiled spring B17 is joined by one end to said clutch-lever and by the other end to a stationary portion of the machine in such relation as to normally hold the clutch B15 in engagement with the spurgear B11.

B18 is a cam-wheel surrounding and keyed to the shaft B10 and having the cam projections 512.

B10is a relatively large ratchet-Wheel located beneath the cam wheel B18 and lnounted around a shaft B20, upon which shaftis mounted a cam-wheel B21, having the laterally-directed cam face or faces 521. A shiftable pawl 51J is arranged between said ratchet-wheel and said camwvheel B111, with one end bearing upon the periphery of said ratchet-wheel and the other end drawn into the path of the cam projections 518 by a coiled spring 310. (See Figs. 4 and 7.) A gravity-pawl p19 also bears upon the periphery of said ratchet-wheel adjacent to the pawl 510 and prevents reverse movement of said ratchet-wheel and the parts thereto connected. From the foregoing it will be seen that a series of rotations of the shaft B10 will rotate the ratchet-Wheel B10, shaft B20, and cam-wheel B21 sufciently to bring one of the cam-faces 521 into engagement with the free end of the clutch-lever B10,

' whereby said end is forced outward from said B11, whereby the clutch B15 is drawn out of engagement with the spur-gear B11, so that said spur-gear becomes stationary and movement is no longer transmitted to the spur-gear E and shaft E.

The cam-faces 521 may be secured to the camwheel B21 in such manner as to be both removable and readily adjustable, to the end that the number of cords in a fabric may be increased or decreased and the spaces between the cords varied. For example, if the said camfaces are equally spaced upon said cam-wheel the cords in the fabric will be equally spaced; but if two or more of said cam-faces are placed near each other in adjacent radii of the calnwheel the cords in the fabric will be correspondingly grouped. Thus if it is desired to place in the fabric first one cord and later two cords standing near each other a camface 521 is first located alone and then two other cam-faces 521 are located near each other at a suitable distance from the irst of said cam-faces. Said cam-faces are thus made removable and adjustable by being secured to said cam-wheel B21 by a bolt B22, extending from each such cam-face through a slot 522 in Said wheel.

At the left end or foot of the machine a mutilated gear E2 surrounds and is secured to the shaft E. Said mutilated gear has upon its periphery four equidistant teeth e3. The roll D has at the foot end of the machine a spur-gear D1, which meshes into a'r'idle-gear D5, which is secured to a fixed horizontal shaft projecting from the foot end of the carriage A. Upon the same shaft and joined to the spur-gear D5 is a spur-gear D0, which is in plane with the mutilated gear E3 and of proper diameter to have its teeth reach into the path of the teeth e2 of said mutilated gear. The rolls D and D2 may or may not be provided with intermeshing gears D7. It will now be seen that with each quarter rotation of the mutilated gear E3 the rolls D and D2 will be rotated through a few degrees. The extent of this rotation of said rolls is sufficient to move a point in the circumference of one of said rolls through a distance equal to the diameter of one of said coils of the fabric, the precise distance being attained by establishing the proper ratio of difference between the mutilated gear E2 and the spurgear D1. rlhe length of the intervals between these partial rotations of the rolls D and D2 is dependent upon the velocity of the mutilated gear E2, and this velocity is dependent upon the ratio of difference between the mutilated gear E11 and the gears intervening between said mutilated gear and the bandwheel B.

In starting the operation of the machine the fabric F is managed by the operator until enough has been formed to be properly engaged by the mechanism of the machine. Then the marginal or last-finished coil is held parallel to and partially in the groove D by the pins G of the pin-bars G and one of the knife-bars lil, the pins G of one of saidpinbars standing in the coil next to the marginal or 'filial coil and bearing against both of said coils, and the lower edges of the sections H of one of the knife-bars H being pressed into the groove or channel between the tina-l coil and the coil next to the final coil, and the rolls D and D2 tending to draw the fabric away from said pin-bar and knife-bar. `(See Fig. 7.) By this means every marginal coil is brought with great accuracy into the desired relation with the ceiling-axis, or the line which coincides with the axis ofthe new coil as the latter is being projected from the coiler, so that every turn of the marginal coil is in the precise position best adapted to allow the new coil to intertwine at each rotation with said turn. The groove or channel D is thus in accurate relation with every turn of t-he iinal coil, and the new coil in being' projected forward through said groove is guided at every turn into precise relation with each turn of the inal coil. As soon as a coil is completed and cut adjacent to the coiler the pin-bar G and theknife-bar H then in engagement with the fabric must be released, in order that the fabric may be drawn away from the coilingaxis by the fabric-drawing mechanism, and

at the same time the other pin-bar G and` the other knife-bar H must be brought into proper relation to engage the coil succeeding the one which was last engaged by said pin-bar and knife-bar. This is accomplished by alternating the elevation of said pin-bars with one another and said knife-bars with one another. Immediately after the last-finished coil is cut adjacent to the coiler, the pin-bar then in engagement is lowered and the knifebar then in engagement is raised, while immediately following these changes, the other pin-bar ascends and the other knife-bar descends, so that both more into the path of the coil succeeding the one last engaged and arrest the movement of said first-mention ed coil, whereby the movement of the entire fabric is arrested.

As an alternative construction the pins G may rise through the carriage A into the channel D and engage only the marginal coil at the side of the wire of the latter and hold said coil in fixed relation to said groove, as shown in Fig. M, while the knife-bars are located a little rearward, so that the knife-sections Il may press between the marginal coil and the coil next behind the marginal coil. When this construction is adopted, the forward end of the new coil will have to reach around each turn of the marginal coil and also around each pin G', as indicated by the dotted circle in Fig. 13.

The upper pin-bar G is located beneath and has its pins G rising through the openings g in the top of the carriage A. The lower pinbar G is located beneath the upper pinbar and has its pins G rising through openings g in the upper pin-bar between the pins G of the upper pin-bar and through openings g in the top of the carriage A. Each of the pin-bars G has a vertical support resting upon a cam G2 on the shaft E, the extended portions of the cams receiving the supports from one piny-bar alternating in radial relation with the extended portion of the cams supporting the other pin-bar, so that as the shaft E is rotated the pin-bars G are alternately elevated, whereby the pins on the respective bars G are alternately extended upward through the top of the carriage A into the path of the coils of the fabric, one set of Said pins always rising through the top of said carriage, while the othersetof said pins is being drawn downward through said top.

G3 G3 are depending arms attached by their Lipper ends to the carriage A and close to the sides of the pin-bars and serve to so confine the bars G as to allow the latter to move only in a vertical plane. (See Figs. 7 and S.)

The knife-bars H are placed one above the other and secured to the brackets I by means of links H2, one end of each link being hinged to one of said brackets and the other end being hinged to one of said bars, whereby said bars may be moved in a Vertical plane after the manner of a parallel ruler. In this relation both knife-bars wi ll, unless restrained descend and rest between the coils of the fabric F or upon the top of the carriage A. The mechanism controlling these bars allows them to thus alternately descend by gravity.

A spindle A4 extends outward from the foot end of the carriage A parallel to the shaft E, and bears a spur-gear H3 and a cam H4, having cam-faces h4 on the side toward the carriage A', one of said cam-faces being at a sufficient distance from the spindle AL to make contact at each rotation with the end of the upper knife-bar H, and the other of said cam-faces being at a sufiicient distance from said spindle A4 to make contact with the other end of the other knife-bar Il at each rotation, and said cam-faces being located at opposite sides of thespindle A,so that while one is in engagement with its knife-bar the other will be out of engagement with its knifebar and allow the same to rest by gravity between the coils of the fabric, as already described.

The mechanism leading from the shaft E to the pin-bars G and from said shaft to the knife-bars H and from said shaft to the rolls D and 'D2 are properly timed with reference to each other to produce the necessary simultaneous action.

The manner of periodically shifting the car riage A toward and from the coiler is in the main the same as described in said Briggs patent. An arm A5 extends from said carriage toward the shaft E and there supports two rollers a5, one extending to each side of the periphery of a cam J and each presenting to said cam a face to which the line of movement of the carriage iS substantiallyper pendicular. Said cam J differs from the cam shown by said Briggs patent in that it is du- IOO IIC)

plex, being composed of two disk-form sections J each loosely surrounding and separately adjustable upon the shaft E by means of set-bolts J2 and having onthe face toward the adjacent roller a5 one or more cam-faces j', the cam face or faces on the one section J alternating in radial spacing with that of those on the other section. The sections J of the duplex cam J are separated sufficiently to cause each roller to be pressed laterally by the passing of the cam-face on the adjacent cam-section, while the other roller is drawn into the path of a cam-face on the other calnsection, so that when said other cam-face J is rotated past the second roller the movement is reversed. Thus the carriage A is alternately shifted upon the ways A3 a distance equal to the difference between the distance between the rolls a5 and the thickness of the cam J from the plane of the cam-faces at one side of the cam to the pla-ne of the cani-faces at the other side of said cam. This distance may be varied by shifting the cam-sections of the cam J. The precise path of reciprocation of the carriage A may also be varied in location by bodily shifting the cam J toward and from the head of the machine upon the shaft E. The distance through which said carriage reciprocates should be equal to about onehalf the distance between the turns of the coils on the fabric F, in order that such turns may always be brought out of the spiral path through which the new coil is projected to the end that the new coil may run forward in its path and intertwine at each turn with the marginal or last-finished coil without hitting the latter. The radial position of the cam-faces 7" with reference to the shaft E is to be so adjusted as to canse one of said cam-faces to operate immediately after the operation of the knife which cuts the coiladjacent to the coller. L is a knife for cutting the wire adjacent to the coiler as often as a coil is completed.

L is a stationary block over which the wire passes and against which the wire is cut by said knife L. Said knife L is attached to a vertically-reciprocatingbarL2, con fined above in the guide L3 and extending below through a guide-plate L4. The lower end of said bar is surrounded by an expanding coiled spring L5, which has its lower end bearing upon said guide-plate and its upper end resting against a shoulder Z2, and the expansion of said spring keeps said bar and said knife normally elevated away from the block L. From a point below the level of the shaft B10 an anti-friction roller Z6 is Supported by said bar L2 and extends laterally beneath a cam L, surrounding the shaft B10. As the extended portion of said cam passes between said shaft B10 and said roller ZG the latter and the bar L2 and knife L are forced downward, so as to cut, and when said extended portion is passed out of engagement with said roller the latter and said bar and knife are allowed to rise in response to the expansion of said spring L5. The extended portion of said cam L6 is so turned radially upon the shaft B10 as to cause the knife L to operate immediately after the forcing-rolls of the coiler have rotated a sufficient number of times to project a coil of the desired length.

M M are trimming-knives similar to the cutting-knife L, one being located at each end of the machine back of the pin-bars G and knife-barslfl. Ablock M similar to the block L', is arranged in opposition to each knife M. Each knife M is supported by a verticallyreciprocating bar M2 and extends through a guideway M3 above and through the guideplate L4 below and is surrounded at its lower end by an expanding spring M4, which rests at its lower end upon the guide-plate Ll and at its upper end against a shoulder m2. From a point on said bar M2 below the level of the shaft E a roller M5 extends laterally beneath the cam MG, which has four extensions m0, which in passing engage the roller M5 and depress it and the bar M2 and knife M, and when passed said roller is released, so that it and said bar and knife may rise in response to the expansion of the spring M3. The function of said knives M is to cut each coil of the finished fabric as the latter passes toward the rollers D and D2, in order that the fabric may be trimmed even at its ends.

The machine illustrated by the drawings being of sufficient length to coil a fabric twice as long as is needed for one bed-bottom, said fabric must be cut at or near the middle, and in order that the same need not be done after the removal of the fabric from the machine we have devised automaticcutting mechanism to cut the fabric at or near the middle while the fabric is passing away from the machine. At the middle of the rear of the carriage A a knife-arch O rises from said frame and carries the downward-directed knife O. The upright portion of said arch is fiat and has one edge directed forward and the other rearward, in order that the two sections into which the fabric is being cut need separate only a little to pass said arch.

O2 is a vertically-reciprocating knife confined in a guideway O3 on the carriage A and held normally in the elevated position by a contracting-spring O, having its upper portion attached to said knife and its lower end to a stationary portion of the carriage A. The lower end of said knife is attached to one end of atilting lever O5, the other end of which lever extends into the path of cam-pins O7 upon a cam-wheel O, surrounding the shaft E. Said cam-pins depress the free end of the lever O5, and thus cause the other end to raise the knife O2, and said cam-pins are preferably of such number as will cause said knife to make a separate cut for each coil of the fabric as the latter passes said knife.

We have found it advantageous to use a guide-bar I immediately behind the knifebars H and pin-bars G and above the fabric F and the top of the carriage A to hold the fabric down uniformly in the same plane imroo IZO

mediately above the top of the carriage A', in order that the fabric may always be in the same relation to the pins G and the knifeedges of the knife-bars 1I. Said bar P is supported from above by attachmentto the arches I by bolts P', passing loosely through said arch and surrounded by an expanding coiled spring, which causes said bar to bear slightly and yieldingly upon the fabric F.

Q is a reel located at the rear of and parallel tothe rollers D and D2 and suitably supported from the frame A by bracketsqor otherwise, Figs. 2 and 1l, which may be used to receive the fabric F after leaving said rolls D and D2. Said reel is turned by a belt Q', surrounding a band-wheel Q2 on the shaft of the roll D2 or D', and the band-wheel Q3, surrounding the shaft of the reel Q. As a given velocity of the reel Q will gradually increase the drawing of the reel upon the fabric as the quantity of fabric upon the reel increases, it is desirable that the velocity of the reel be gradually reduced as the work progresses. Provision is made for this by arranging the belt Q so loosely as to cause it to slip when the desired tension of the fabric between the rolls and the reel Q has been attained and to again turn said reel when sufiicient of the fabric has passed between the rolls D and D2 to again slacken the tension of the fabric between said rolls and said reel. A uniform tension of the belt Q is attained by means of the tightening-wheel Q4, which rests idly upon the belt Q and is confined in such position by an arm Q5, journaled at one end to said wheel Q4 and hinged by the other end to the frame A. It will be seen that the reel Q. may be omitted and the fabric allowed to fall upon the floor or upon any other support that may be arranged at the rear of the machine. It will be seen, also, that when the, reel Q and the rolls D and D2 are present in the machine there is a double fabric-drawing mechanism, but that. the reel Q has no infiucnce in drawing the fabric at the coilingaxis, for the rolls D and D2 are positively geared to the shaft E and have therefore a positive and restricted motion,and the fabric can move away from the ceiling-axis only as permitted and caused by the rolls D and D2. If the rolls D and D2 should be omitted and the reel Q subsequently belted to some other moving portion of the machine, then said reel would draw the fabric directly from the coiling-axis. XVe have also in practice allowed the fabric F to hang by gravity directly over the rear of the machine without engagement by the rolls D D2 and shift away from the coiling-axis as often as released by the pins G and knife-edges II; but this means of operating is not as satisfactory as mechanism which acts with greater force and greater uniformity. It will be seen, also, that two distinct mechanisms are provided for engaging and releasing the marginal coil and that cach of these mechanisms is duplex. The pins G and the bars G, supporting said pins, are in themselves a mechanism for grasping and releasing the marginal coil, as there are two bars each having its own set of pins alternating in elevation and engagement. Hence this mechanism is duplex. VEach of these pin-bars and the pins thereon constitutes a reciprocating mechanism for engaging and releasing the marginal coil. Itis to be noted,also,that the marginal coil is engaged by the pins G in either of the arrangements shown by Figs. 13 and If-i. The bars II and the knife-edges thereon constitute a mechanism for engaging and releasing the marginal coil, and they are reciprocating mechanism for this purpose, and each such barand the knife-edges thereon constitute a reciprocating mechanism for engaging and releasing the marginal coil.
